Technical Analysis

VISCOSITY DYNAMICS AND HYDRAULIC OIL SPECIFICATIONS

Viscosity is the determining parameter for the volumetric efficiency of a hydraulic pump. The optimal kinematic viscosity for most industrial hydraulic systems falls within the range of 16-40 cSt (centistokes), typically achieved at operating temperatures from 35C to 55C. However, when ambient temperature drops to -25C, the kinematic viscosity of standard industrial oils of ISO VG 46 or ISO VG 68 class increases exponentially. According to laboratory testing, standard all-season ISO VG 46 oil below zero can reach viscosities exceeding 2000-5000 cSt, leading to critical thickening. For operation at -25C and below, hydraulic fluids with a high Viscosity Index (VI) must be used. The VI reflects the stability of kinematic viscosity under temperature fluctuations. For arctic specifications, the VI must exceed 150. Specialized fluids such as Shell Tellus S4 VX 32 achieve a VI of 300 with a pour point of -60C. Fully synthetic biodegradable esters (HEES), such as BIONA Premium Hydraulic Oil ISO VG 32, offer a VI exceeding 170 and a pour point below -50C. When selecting high-viscosity fluids, the effect of polymer thickener (VI improver) degradation under shear stress in pumps must be considered. The engineering rule states that minimum allowable component viscosity values must be increased by 30% to compensate for viscosity loss due to polymer chain destruction. As additives in modern hydraulic oils, zinc dialkyldithiophosphates (ZDDP) are used at concentrations of at least 900 ppm, forming protective anti-friction films on metal surfaces of piston pumps. However, for environmentally sensitive zones (and in biodegradable HEES oils), zinc-free additive packages are required, which must pass stringent Thermo-Oxidative Stability Tests (TOST).

HYDRODYNAMIC CAVITATION AND DE-AERATION

Excessive viscosity during cold start creates two destructive phenomena: suction pressure drop and cavitation. The maximum allowable viscosity at start for gear and axial piston pumps is limited to 1500-1620 cSt (approximately 7500 SUS). If viscosity exceeds this limit, the pump is physically incapable of drawing oil from the reservoir. The suction line experiences resistance, causing pressure to drop below the vapor pressure of the oil (critical reduction of Net Positive Suction Head, NPSH). Per regulations, vacuum at the pump inlet must not exceed 5 inches of mercury (13 cm Hg), and flow velocity in the suction line must be limited to 2.5 m/s (8 ft/s). Exceeding these parameters causes instantaneous formation of vapor-gas bubbles, which collapse in the high-pressure discharge zone causing micro-hydraulic shocks that destroy metal surfaces of blades and pistons. The situation is exacerbated by the compact dimensions of hydraulic tanks in mobile shredders. For example, the Arjes Impaktor 250 has a hydraulic tank of only 18 gallons (approximately 68 liters) with a 173 HP (175 HP) Volvo Penta diesel engine. Such a small reservoir volume means minimal fluid residence time, hindering natural de-aeration. Polymer thickeners (VI improvers) also negatively affect the air-release properties of oil, which can be verified using the foam test (ASTM D892).

COLD START MECHANICS OF ASYNCHRONOUS SHAFTS

The Arjes Impaktor series uses an asynchronous twin-shaft drive with rapid reverse capability. At -25C, cold starting the diesel engine (Volvo Penta TAD581VE) drives the hydraulic pumps, which must overcome the peak resistance of thickened oil in the hydraulic motor circuits and Bonfiglioli gearboxes. If the dynamic viscosity of the hydraulic fluid (measured by the Brookfield method, ASTM D2983) exceeds safe limits (typically 750-2000 cP for cold start), the system will experience a step increase in pressure. Pressure in the circuits of heavy hydraulic shredder systems is typically regulated by relief valves at 3190-3500 PSI (220-240 bar). With abnormally high viscosity, compensation valves trip before the shafts begin rotation, leading to oil overheating through viscous shearing and a 10-20% drop in volumetric efficiency for every 200 cSt above nominal. For successful startup and equipment survival at -25C, pre-heating procedures for reservoirs (immersion heaters) must be implemented, along with strict use of ISO L-HV 32 class oils or specialized Shell Tellus S4 VX series fluids.
